Both score 87/100 and both represent modern stability — support built into geometry rather than hard plastic posts. The Guide 17 does it with a wide base and raised foam sidewalls that cradle the foot, on a softer 28 HC midsole with a contemporary 8mm drop at 275g. The Adrenaline GTS 23 uses GuideRails on a firmer 30 HC platform with a traditional 12mm drop at 298g. Price is near-identical ($128–$140 vs $118–$140); the Guide has the marginally wider toebox (95mm vs 94mm).

Who should buy which
Choose the Guide 17 if you want stability that feels like a neutral shoe — the sidewall approach is the least intrusive in the category, and the lower drop plus lighter weight give it the more modern ride.
Choose the Adrenaline GTS 23 if you're a heel striker who benefits from the 12mm drop, or you specifically want correction that activates late in the stride — GuideRails do exactly that, which is why physios keep prescribing them.
